Are you talking an actual aftermarket fuel injector or something that controlls the fuel amount for situations like when you add aftermarket exh and stuff? If your talking about an actuall new injector then I am unaware of one yet. Doesnt mean it isnt out there yet I just havent seen or heard of it.

Give Terry at GeisickPerformance.com a call. I don't think they have them listed on their website, but I know they have several sizes of injectors in stock.

I don't know if spray pattern will give any noticable increase power but the stock injectors are pretty easy to max out on duty cycle, which is not a good thing to do for several reasons. Another big advantage of a larger injector is the ability to run methanol, turbos, and othe rmods that require a lot more fuel....

I called GeisickPerformance this morning and talked to them about the injectors. They have a few different choices depending on application. They were very good to work with and I just ordered a larger injector. They have them custom built to work on the Raptor, so it's not just a renamed Bosch or Denso injector. I'll keep everyone informed when it arrives and see if I can snap some pics.

hey glamis just remember if you get that big injector even though you got the pc3 i will NOT compensate for fuel when boost starts to go in. even though you will have a big inj. they are rated at the certain cc at usually 43.5psi fuel rail pressure max. the stock yamaha is rated at 46psi. so the injector regardless what you put in is gonna be above max duty cycle. im working on that right now geisick is the guy with injectors but he still has to test the 750cc injector he wants to run in a alcohol setup to see how they work. your gonna have to modify the fuel system as im doing right now. i was guided by the guy that builds the fireball hayabusa on that.. but its gonna work ill try to post some pics finally got software to upload pics on to the computer. good luck to all.. see you guys at 4sw's race#2 dumont
